The OECD Nuclear Energy Agency has issued a report calling for more-detailed information on tracking the decay heat of spent nuclear fuel from light water reactors. According to the NEA, the report highlights the increasing importance of accurate decay heat estimations due to evolving fuel characteristics, including higher initial fuel enrichment, increased burn-up rates, and extended reactor cycle lengths.

The report, Summary of the NEA Assessment on Spent Nuclear Fuel Decay Heat for Light Water Reactors, summarizes the findings of a subgroup of the NEA’s Working Party on Nuclear Criticality Safety (WPNCS), which ran from January 2022 to January 2024.

Global engineering company Amentum announced plans on Thursday to create 3,000 new jobs over the next four years on the back of growth in nuclear power and defense in the United Kingdom.

The announcement follows President Donald Trump’s state visit to the U.K., during which a number of deals between the two countries were announced.

Nuclear Waste Services, the radioactive waste management subsidiary of the United Kingdom’s Nuclear Decommissioning Authority, has reported on its inaugural year of the National Youth Forum on Geological Disposal. NWS set up the initiative, in partnership with the environmental consultancy firm ARUP and the not-for-profit organization The Young Foundation, to give young people the chance to share their views on the government’s plans to develop a geological disposal facility (GDF) for the safe, secure, and long-term disposal of radioactive waste.

The Department of Energy’s Office of Environmental Management said the Idaho Cleanup Project (ICP) has recycled more than 2,100 tons of noncontaminated metal debris since 2022 as it works to demolish three legacy Naval Nuclear Propulsion Program prototypes at the Idaho National Laboratory Site, saving taxpayers nearly $2 million in disposal costs while advancing the project’s environmental goals.

Energy Secretary Chris Wright issued a statement on September 9 denying reports that the Department of Energy plans to terminate the Waste Isolation Pilot Plant (WTP) at the Hanford Site in Washington state.

Demonstrating the beneficial reuse of equipment among Department of Energy cleanup sites, the DOE’s Office of Environmental Management transferred TRUPACT-III shipping equipment from its Savannah River Site in South Carolina to the Idaho Cleanup Project at the Idaho National Laboratory Site. This collaboration shows how DOE-EM drives efficiency, focusing on priorities and reining in costs without sacrificing safety or effectiveness, the DOE said.

The Department of Energy’s Office of Environmental Management announced yesterday the awards of five basic ordering agreements to conduct nationwide low-level and mixed low-level radioactive commercial waste treatment services at commercial waste treatment facilities of DOE contractors throughout the United States.

The Environmental Protection Agency has approved the addition of two new waste emplacement panels at the Waste Isolation Pilot Plant, the Department of Energy’s geologic repository for defense-related transuranic waste in New Mexico.

Holtec International has submitted a license termination plan (LTP) for Oyster Creek nuclear power plant to the Nuclear Regulatory Commission, a milestone in the decommissioning of the boiling water reactor, which operated from 1969 to 2018. Holtec took over Oyster Creek’s license from Exelon Generation in 2019 for the immediate decommissioning of the plant, located in Forked River, N.J.

The Nuclear Waste Technical Review Board announced it will hold a public meeting on Wednesday, August 27, to review information on the Department of Energy’s activities to manage spent nuclear fuel and high-level radioactive waste and to receive program updates from the DOE’s Office of Nuclear Energy.

The Trump administration has dismissed seven of the (formerly) eight board members of the Nuclear Waste Technical Review Board, the independent federal agency tasked with evaluating the technical and scientific validity of Department of Energy activities related to managing and disposing of high-level radioactive waste and spent nuclear fuel.

Researchers with the Massachusetts Institute of Technology, working with scientists from Lawrence Berkeley National Laboratory and the University of Orléans, have modeled radionuclide behavior in deep geologic formations, offering a tool for developing a defensible safety case for the underground disposal of radioactive waste.

The Nuclear Regulatory Commission is considering allowing Entergy to use a portion of the decommissioning trust fund (DTF) for the Arkansas Nuclear One nuclear power plant to dispose of several major radioactive components (MRC) that have been taken out of service at the two-unit pressurized water reactor.

The American Nuclear Society joined seven other organizations to send a letter to Energy Secretary Christopher Wright on July 8, asking to meet with him to discuss “the restoration of a highly functioning program to meet DOE’s legal responsibility to manage and dispose of the nation’s commercial and legacy defense spent nuclear fuel (SNF) and high-level radioactive waste (HLW).”

The World Bank and the International Atomic Energy Agency signed an agreement last week to cooperate on the construction and financing of advanced nuclear projects in developing countries, marking the first partnership since the bank ended its ban on funding for nuclear energy projects.

Nagra, Switzerland’s national cooperative for the disposal of radioactive waste, has published its general license applications for a deep geologic repository and separate spent fuel encapsulation plant, making the documents publicly available on a digital platform.

The Department of Energy’s Office of Environmental Management and its cleanup contractor CH2M Hill BWXT West Valley (CHBWV) completed the on-time removal of the Main Plant Process Building at the West Valley Demonstration Project (WVDP) in New York. Located 35 miles south of Buffalo, the 150-acre WVDP site is home to the only commercial spent nuclear fuel reprocessing facility to operate in the United States.

The Department of Energy’s Office of Environmental Management said that crews at its Hanford Site in Washington state are preparing for the site’s first-ever transfer of radioactive waste from one of its large underground tanks, Tank AP-106, to the Waste Treatment and Immobilization Plant (WTP).
